Title: Suspension polymerisation of vinyl monomers
Inventor: LOVE THOMAS
IPC: C08F14/06
Filed: 1959-09-01
Abstract: Vinyl chloride and mixtures of vinyl monomers consisting principally of vinyl chloride are polymerized in suspension in water in the presence of (a) monomer-soluble free-radicalproducing initiators, (b) protective colloids and (c) the direct reaction products of alkyl or alkyl aryl sulphonic acids containing not less than 8 carbon atoms with the oxides or hydroxides of alkaline earth metals.  Specified protective colloids are cellulose derivatives, polyvinyl alcohol and salts of polyacrylic acid.

Title: New adducts of polyepoxides and cycloaliphatic di-primary diamines, process for their manufacture and use
IPC: C08G59/00
Filed: 1968-06-21
Abstract: 1,204,224. Curing epoxy resins. CIBA Ltd. 21 June, 1968 [22 June, 1967], No. 29783/68. Heading C3B. Adducts useful in curing epoxy resins are prepared from a polyepoxide (I) and a cycloaliphatic-aliphatic diprimary diamine (II) in which the first amino group is attached to an aliphatic side chain and the second amino group is attached to an endocyclic carbon atom of the cycloaliphatic ring. From 0.6 to 1.2 moles of II are used per epoxide equivalent of I. Adduct formation may take place at 60-180 C. Examples of II are: 3 - aminomethyl - 3,5,5 - trimethylcyclohexylamine; 1,8 - diamino - p - menthane; and 2 - aminomethylcyclopentylamine. The polyepoxide reacts preferentially with the first aliphatic amino group having the second cycloaliphatic amino group available for subsequent curing. Compositions of epoxy resins and the above adduct may be used in conjuction with conventional additives in moulding powders and coating compositions which are shelf-stable at ambient temperatures.

Title: Improvements in boiler feed water supply systems
IPC: F22D11/06
Filed: 1921-11-08
Abstract: 191,884. Fothergill, H. Nov. 8, 1921. Feed-water, supplying.-In a steam-condensing and feedwater supply plant in which the condensate is removed from the condenser and delivered to the boilers by rotary pumps, a throttle valve on the discharge side of the feed-pump is closed automatically when the pressure on the suction side of the pump falls below a predetermined value, and opens again when the pressure rises, this maintaining a substantially uniform pressure on the suction side. The escape of water leaking past a piston 4, Fig. 2, attached to the throttle valve is controlled by a needle valve 6, which is forced upon its seat against the action of a spring by the pressure in the suction pipe E acting on a diaphragm 6<a> secured to the valve stem. In a modification, a duplex valve 1, Fig. 3, in the discharge pipe 2 is held in its closed position by a spring 10 when the pressure in the suction pipe E is below the predetermined limit, and is opened when this pressure acting on a piston 11 rises above the limt. A by-pass valve 9 opens when the load on the main turbine or engine falls below a certain point, and admits water from the feed or reserve tank to the condenser, as described in Specification 135,885, [Class 32, Distilling &c.].

Title: Improvements in two-stroke cycle internal combustion engines
IPC: F01L5/00
Filed: 1920-10-26
Abstract: 164,706. Mathauser, S. June 10, 1920, [Convention date]. Addition to 153,256. Valves.-The invention consists in (1) provid ing a yielding cylinder cover, and a yielding end upon the head of the piston which abuts against the cover, and (2) actuating the outer piston 2<1> so that it moves towards the cylinder head at a faster rate than the inner piston 3. According to the construction shown in Dig. 1, the cylinder cover 7 is held in its lowermost position hv springs 37 which vield when the cover is engaged by the head of the outer piston 2<1>. A yielding end on the piston 2<1> comprises a member 2<11> forced outwards by springs 29. According to a modified construction, the yielding end of the piston is dispensed with, and the cylinder cover is acted upon by a helical-plate spring. In both constructions, the explosion occurs before the piston 2<1> reaches the end of its upstroke, the combustion gases above the piston being transferred to the space between the pistons during the expansion stroke of the inner piston 3. The cycle of operations otherwise is the same as that described in the parent Specification.

Title: Improvements in or relating to means for indicating the rate of flow of a liquid
IPC: G01P5/14
Filed: 1930-10-09
Abstract: 357,390. Liquid flow indicators. HOVEMAN, W. A. and HOVEMAN, F. C., 146A, Queen Victoria Street, London. Oct. 9, 1930, No. 30309. [Class 97 (ii).] Apparatus for indicating the rate of flow of : liquid comprise a visible indicator adapted to be carried with the liquid stream and means to allow the indicator to move out of the path of the liquid after a predetermined travel therein so that i may subsequently return to a posi tion for starting a fresh indication. The Figure shows the application of the invention to apparatus for adding alumina to water in proportion to the rate of flow. The inlet end of a Venturi tube 1 in the main pipe 2 is connected by a pipe 4 to the container 3 for alumina which is connected to the throat of the Venturi tube by a pipe 5. A block 15 traversed by channels 16, 17, 18 as shown is interposed in the pipe 4. A celluloid or glass capillary tube 9, 10 of U-shape is connected to the ends of the channels 17, 18 respectively by cup-shaped joints 21. A cock 19 is provided in the channel 16. When the cock is open the flow is through the channel 16, but when closed the flow is through the capillary tube 19, a drop of mercury 29 being carried with the stream and indicating the rate of flow by its movement across the scale 27. When the mercury reaches the cup 21 it is pushed aside from the stream and returns to the bottom of the U -tube only when the cock 19 is again opened. The tube may be of restricted diameter at the bottom in order to bring the mercury quickly into motion. Where the flow through the pipe 4 is too great to pass through the capillary tube, the cock 19 may be arranged even in the closed position to byepass a certain definite proportion of the stream.

In an automatic titration (or like mixture control system) the deviation of the electro-chemical potential of a solution from a desired valve controls a pulse-generator to provide constant shape pulses having a p.r.f. varying with the error signal, and these pulses control the addition of reagent e.g. by electrolytic generation. As described, Fig. 5, a pair of cells 10 which may be selectively switched to the measuring control system are provided for determining CO 2  and SO 2  respectively. CELL CONSTRUCTION: each cell comprises three compartments separated by porous porcelain diaphragms, 15, and containing an Ag-AgCl reference electrode 20, a glass indicator electrode 19, a generator electrode 18 and an anode 21. Gas is admitted through an electromagnetic valve 22 and pipe 17. ELECTROLYTE: For CO 2  a mainly barium perchlorate solution is used, and for SO 2  a mainly sodium sulphate solution. MEASUREMENT CIRCUIT DETAILS: pulse generation and shaping is conventional; a low-pass filter 26 is used to reject "generator" pulses from the error signal circuit; measurement is made by a pulse counter 32; since the end of a titration is asymtotic the counter is tripped at a small acceptable error signal value; since the F.M pulse generator is only linear up to about 5v. input an upper-limit error-signal control 34 is arranged to trip the gas supply valves at this value.
